Put these permission outside the <application> tag preferable before the tag, I tried it and it works for me.

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Ensure that any user-specific configs are included!

If none of the other answers on this page for you work, here's what I ran into after hours of floundering around.

I used user-specific configurations, with Sites specified as my UserDir in /private/etc/apache2/extra/httpd-userdir.conf. However, I was forbidden access to the endpoint http://localhost/~jwork/.

I could see in /var/log/apache2/error_log that access to /Users/jwork/Sites/ was being blocked. However, I was permitted to access the DocumentRoot, via http://localhost/. This suggested that I didn't have rights to view the ~jwork user. But as far as I could tell by ps aux | egrep '(apache|httpd)' and lsof -i :80, Apache was running for the jwork user, so something was clearly not write with my user configuration.

Given a user named jwork, here was my config file:

/private/etc/apache2/users/jwork.conf

<Directory "/Users/jwork/Sites/">
    Require all granted
</Directory>

This config is perfectly valid. However, I found that my user config wasn't being included:

/private/etc/apache2/extra/httpd-userdir.conf

## Note how it's commented out by default.
## Just remove the comment to enable your user conf.
#Include /private/etc/apache2/users/*.conf

Note that this is the default path to the userdir conf file, but as you'll see below, it's configurable in httpd.conf. Ensure that the following lines are enabled:

/private/etc/apache2/httpd.conf

Include /private/etc/apache2/extra/httpd-userdir.conf

# ...

LoadModule userdir_module libexec/apache2/mod_userdir.so

To avoid this warning, instead of using:

parseInt("999", 10);

You may replace it by:

Number("999");

^{Note that parseInt and Number have different behaviors, but in some cases, one can replace the other.}

I like what Franz said, because is what I'm using :P

var date_ini = new Date($('#id_date_ini').val()).getTime();
var date_end = new Date($('#id_date_end').val()).getTime();
if (isNaN(date_ini)) {
// error date_ini;
}
if (isNaN(date_end)) {
// error date_end;
}
if (date_ini > date_end) {
// do something;
}

Just use:

overflow: hidden;
white-space: nowrap;

Using Storyboard-

Create-

• Go to main.storyboard (This can be found in theProject Navigator on the left hand side of your Xcode) and drag and drop the "Activity Indicator View" from the Object Library.

• Go to the header file and create an IBOutlet for the UIActivityIndicatorView-

   @interface ViewController : UIViewController
  
       @property (nonatomic,strong) IBOutlet UIActivityIndicatorView *activityIndicatorView;
  
   @end
  

• Establish the connection from the Outlets to the UIActivityIndicatorView.

Start:

Use the following code when you need to start the activity indicator using following code in your implementation file(.m)-

 [self.activityIndicatorView startAnimating];

Stop:

Use the following code when you need to stop the activity indicator using following code in your implementation file(.m)-

 [self.activityIndicatorView stopAnimating];

Works for me. You probably want to multiplz it with 1000, since what you get are the seconds from 1970 and you have to pass the milliseconds from jan 1 1970

With RestAssurd you can also do the following:

String path = baseApiUrl; //This is the base url of the API tested
    URL url = new URL(path);
    given(). //Rest Assured syntax 
            contentType("application/json"). //API content type
            given().header("headerName", "headerValue"). //Some API contains headers to run with the API 
            when().
            get(url).
            then().
            statusCode(200); //Assert that the response is 200 - OK

Assuming that onMove is an event handler, it is likely that its context is something other than the instance of MyContainer, i.e. this points to something different.

You can manually bind the context of the function during the construction of the instance via Function.bind:

class MyContainer extends Component {
  constructor(props) {
    super(props);

    this.onMove = this.onMove.bind(this);

    this.test = "this is a test";
  }

  onMove() {
    console.log(this.test);
  }
}

Also, test !== testVariable.

I find this quite tricky, but there is some information on it here at the MatPlotLib FAQ. It is rather cumbersome, and requires finding out about what space individual elements (ticklabels) take up...

Update: The page states that the tight_layout() function is the easiest way to go, which attempts to automatically correct spacing.

Otherwise, it shows ways to acquire the sizes of various elements (eg. labels) so you can then correct the spacings/positions of your axes elements. Here is an example from the above FAQ page, which determines the width of a very wide y-axis label, and adjusts the axis width accordingly:

import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))

def on_draw(event):
   bboxes = []
   for label in labels:
       bbox = label.get_window_extent()
       # the figure transform goes from relative coords->pixels and we
       # want the inverse of that
       bboxi = bbox.inverse_transformed(fig.transFigure)
       bboxes.append(bboxi)

   # this is the bbox that bounds all the bboxes, again in relative
   # figure coords
   bbox = mtransforms.Bbox.union(bboxes)
   if fig.subplotpars.left < bbox.width:
       # we need to move it over
       fig.subplots_adjust(left=1.1*bbox.width) # pad a little
       fig.canvas.draw()
   return False

fig.canvas.mpl_connect('draw_event', on_draw)

plt.show()

It's because you aren't giving the un-hovered state a right attribute.

right isn't set so it's trying to go from nothing to 0px. Obviously because it has nothing to go to, it just 'warps' over.

If you give the unhovered state a right:90%;, it will transition how you like.

Just as a side note, if you still want it to be on the very left of the page, you can use the calc css function.

Example:

right: calc(100% - 100px)
                     ^ width of div

You don't have to use left then.

Also, you can't transition using left or right auto and will give the same 'warp' effect.

div {_x000D_
    width:100px;_x000D_
    height:100px;_x000D_
    background:red;_x000D_
    transition:2s;_x000D_
    -webkit-transition:2s;_x000D_
    -moz-transition:2s;_x000D_
    position:absolute;_x000D_
    right:calc(100% - 100px);_x000D_
}_x000D_
div:hover {_x000D_
  right:0;_x000D_
}

<p>_x000D_
  <b>Note:</b> This example does not work in Internet Explorer 9 and earlier versions._x000D_
</p>_x000D_
<div></div>_x000D_
<p>Hover over the red square to see the transition effect.</p>

CanIUse says that the calc() function only works on IE10+

I know this question is resolved but, for the benefit of anyone else reading it; if you have all of the types involved as strings, you could do this as a one liner:

IYourInterface o = (Activator.CreateInstance(Type.GetType("Namespace.TaskA`1[OtherNamespace.TypeParam]") as IYourInterface);

Whenever I've done this kind of thing, I've had an interface which I wanted subsequent code to utilise, so I've casted the created instance to an interface.

In the first instance you are trying to create what is called a jagged array.

double[][] ServicePoint = new double[10][9].

The above statement would have worked if it was defined like below.

double[][] ServicePoint = new double[10][]

what this means is you are creating an array of size 10 ,that can store 10 differently sized arrays inside it.In simple terms an Array of arrays.see the below image,which signifies a jagged array.

http://msdn.microsoft.com/en-us/library/2s05feca(v=vs.80).aspx

The second one is basically a two dimensional array and the syntax is correct and acceptable.

  double[,] ServicePoint = new double[10,9];//<-ok (2)

And to access or modify a two dimensional array you have to pass both the dimensions,but in your case you are passing just a single dimension,thats why the error

Correct usage would be

ServicePoint[0][2] ,Refers to an item on the first row ,third column.

If you can get SSH to it you can an SSH Port-forwarded SVN server.

Use SSHs -L ( or -R , I forget, it always confuses me ) to make an ssh tunnel so that

127.0.0.1:3690 is really connecting to remote:3690 over the ssh tunnel, and then you can use it via

svn co svn://127.0.0.1/....

A foreign key always requires an index. Without an index enforcing the constraint would require a full table scan on the referenced table for every inserted or updated key in the referencing table. And that would have an unacceptable performance impact. This has the following 2 consequences:

• When creating a foreign key, the database checks if an index exists. If not an index will be created. By default, it will have the same name as the constraint.
• When there is only one index that can be used for the foreign key, it can't be dropped. If you really wan't to drop it, you either have to drop the foreign key constraint or to create another index for it first.

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

To avoid error on null value you can use this code:

{{ game.gameDate ? game.gameDate|date('Y-m-d H:i:s') : '' }}

Yes, for react,

for becomes htmlFor

class becomes className

etc.

For Android .so files, the NDK toolchain comes with the required tools mentioned in the other answers: readelf, objdump and nm.

simply iterate over the list then check the properties of each object.

for (var i = 0; i < jsonObj.length; ++i) {
    if (jsonObj[i]['Id'] === '3') {
        jsonObj[i]['Username'] = 'Thomas';
    }
}

I had this error message because I was trying to import a component in a new module instead of importing the other module where my component was declared.

Removing the component import from my new module and importing the other module solved it for me.

"UPDATE TableName SET TableField = TableField + 1 WHERE SomeFilterField = @ParameterID"

Option 1

In your index.js file (i.e. webpack entry) add a require to your index.html via file-loader plugin, e.g.:

require('file-loader?name=[name].[ext]!../index.html');

Once you build your project with webpack, index.html will be in the output folder.

Option 2

Use html-webpack-plugin to avoid having an index.html at all. Simply have webpack generate the file for you.

In this case if you want to keep your own index.html file as template, you may use this configuration:

{
  plugins: [
    new HtmlWebpackPlugin({
      template: 'src/index.html'
    })
  ]
}

See the docs for more information.

This is a question of style (or preference) since the interpreter does not care. Personally I would try not to make the final statement of a function which returns a value at an indent level other than the function base. The else in example 1 obscures, if only slightly, where the end of the function is.

By preference I use:

return A+1 if (A > B) else A-1

As it obeys both the good convention of having a single return statement as the last statement in the function (as already mentioned) and the good functional programming paradigm of avoiding imperative style intermediate results.

For more complex functions I prefer to break the function into multiple sub-functions to avoid premature returns if possible. Otherwise I revert to using an imperative style variable called rval. I try not to use multiple return statements unless the function is trivial or the return statement before the end is as a result of an error. Returning prematurely highlights the fact that you cannot go on. For complex functions that are designed to branch off into multiple subfunctions I try to code them as case statements (driven by a dict for instance).

Some posters have mentioned speed of operation. Speed of Run-time is secondary for me since if you need speed of execution Python is not the best language to use. I use Python as its the efficiency of coding (i.e. writing error free code) that matters to me.

you have to replace empty strings ('') with np.nan before converting to float. ie:

df['a']=df.a.replace('',np.nan).astype(float)

There is an animationend Event that can be observed see documentation here, also for css transition animations you could use the transitionend event

There is no need for additional libraries these all work with vanilla JS

document.getElementById("myDIV").addEventListener("transitionend", myEndFunction);_x000D_
function myEndFunction() {_x000D_
 this.innerHTML = "transition event ended";_x000D_
}

#myDIV {transition: top 2s; position: relative; top: 0;}_x000D_
div {background: #ede;cursor: pointer;padding: 20px;}

<div id="myDIV" onclick="this.style.top = '55px';">Click me to start animation.</div>

The problem is your dataType and the format of your data parameter. I just tested this in a sandbox and the following works:

C#

    [HttpPost]
    public string ConvertLogInfoToXml(string jsonOfLog)
    {
        return Convert.ToString(jsonOfLog);
    }

javascript

<input type="button" onclick="test()"/>

    <script type="text/javascript">

        function test() {
            data = { prop: 1, myArray: [1, "two", 3] };
            //'data' is much more complicated in my real application
            var jsonOfLog = JSON.stringify(data);

            $.ajax({
                type: 'POST',
                dataType: 'text',
                url: "Home/ConvertLogInfoToXml",
                data: "jsonOfLog=" + jsonOfLog,
                success: function (returnPayload) {
                    console && console.log("request succeeded");
                },
                error: function (xhr, ajaxOptions, thrownError) {
                    console && console.log("request failed");
                },

                processData: false,
                async: false
            });
        }

    </script>

Pay special attention to data, when sending text, you need to send a variable that matches the name of your parameter. It's not pretty, but it will get you your coveted unformatted string.

When running this, jsonOfLog looks like this in the server function:

    jsonOfLog   "{\"prop\":1,\"myArray\":[1,\"two\",3]}"    string

pandas can check for NaT with pandas.isnull:

>>> import numpy as np
>>> import pandas as pd
>>> pd.isnull(np.datetime64('NaT'))
True

If you don't want to use pandas you can also define your own function (parts are taken from the pandas source):

nat_as_integer = np.datetime64('NAT').view('i8')

def isnat(your_datetime):
    dtype_string = str(your_datetime.dtype)
    if 'datetime64' in dtype_string or 'timedelta64' in dtype_string:
        return your_datetime.view('i8') == nat_as_integer
    return False  # it can't be a NaT if it's not a dateime

This correctly identifies NaT values:

>>> isnat(np.datetime64('NAT'))
True

>>> isnat(np.timedelta64('NAT'))
True

And realizes if it's not a datetime or timedelta:

>>> isnat(np.timedelta64('NAT').view('i8'))
False

In the future there might be an isnat-function in the numpy code, at least they have a (currently open) pull request about it: Link to the PR (NumPy github)

No, it is not okay to put a link element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):

“This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.”

After 2 hours of searching it seems google still overrides the yellow color somehow but i for the fix for it. That's right. it will work for hover, focus etc as well. all you have to do is add !important to it.

 input:-webkit-autofill,
 input:-webkit-autofill:hover,
 input:-webkit-autofill:focus,
 input:-webkit-autofill:active {
 -webkit-box-shadow: 0 0 0px 1000px white inset !important;
  }

this will completely remove yellow from input fields

I was facing the same issue in bitbucket, and this worked for me:

line1
##<2 white spaces><enter>
line2

To just get the installed version(s) at the command line, I recommend using net-version.

• It's just a single binary.
• It uses the guidelines provided my Microsoft to get version information.
• It doesn't require the SDK to be installed.
• Or the Visual Studio command prompt.
• It doesn't require you to use regedit and hunt down registry keys yourself. You can even pipe the output in a command line tool if you need to.

Source code is available on github.com

Full disclosure: I created this tool myself out of frustration.

See an example here: http://www.cplusplus.com/reference/stl/vector/insert/ eg.:

...
vector::iterator iterator1;

  iterator1= vec1.begin();
  vec1.insert ( iterator1+i , vec2[i] );

// This means that at position "i" from the beginning it will insert the value from vec2 from position i

Your first approach was replacing the values from vec1[i] with the values from vec2[i]

On more reason could be e-mail verification on github.com

Just log in to github.com and check if there is no message for you, to confirm your e-mail address. Confirm, if necessary.

That's an interesting question. I made this implementation that is just slightly faster (but hardly measurable) when 32-bit release compiling on VC++ 2012. It probably can be improved on a lot. Adding this in your own class in a multithreaded environment would probably give you even more performance gains since there are some reported bottleneck problems with memset() in multithreaded scenarios.

Here you can find the source code Berkley's memset(), which I think is the most common implementation.

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

You need to use dynamic SQL to achieve this; something like:

DECLARE
    TYPE cur_type IS REF CURSOR;

    CURSOR client_cur IS
        SELECT DISTING username
        FROM all_users
        WHERE length(username) = 3;

    emails_cur cur_type;
    l_cur_string VARCHAR2(128);
    l_email_id <type>;
    l_name <type>;
BEGIN
    FOR client IN client_cur LOOP
        dbms_output.put_line('Client is '|| client.username);
        l_cur_string := 'SELECT id, name FROM '
            || client.username || '.org';
        OPEN emails_cur FOR l_cur_string;
        LOOP
            FETCH emails_cur INTO l_email_id, l_name;
            EXIT WHEN emails_cur%NOTFOUND;
            dbms_output.put_line('Org id is ' || l_email_id
                || ' org name ' || l_name);
        END LOOP;
        CLOSE emails_cur;
    END LOOP;
END;
/

Edited to correct two errors, and to add links to 10g documentation for OPEN-FOR and an example. Edited to make the inner cursor query a string variable.

Another way of using pragma:

> table = "foo"
> cur.execute("SELECT group_concat(name, ', ') FROM pragma_table_info(?)", (table,))
> cur.fetchone()
('foo', 'bar', ...,)

You can run this command in Terminal:

react-native --version

This will give react-native CLI version

Or check in package.json under

"dependencies": {
    "react": "16.11.0",
    "react-native": "0.62.2",
}

    protected void Application_EndRequest()
    {
        if (Context.Response.StatusCode == 405 && Context.Request.HttpMethod == "OPTIONS" )
        {
            Response.Clear();
            Response.StatusCode = 200;
            Response.End();
        }
    }

The keyword super doesn't "stick". Every method call is handled individually, so even if you got to SuperClass.method1() by calling super, that doesn't influence any other method call that you might make in the future.

That means there is no direct way to call SuperClass.method2() from SuperClass.method1() without going though SubClass.method2() unless you're working with an actual instance of SuperClass.

You can't even achieve the desired effect using Reflection (see the documentation of java.lang.reflect.Method.invoke(Object, Object...)).

[EDIT] There still seems to be some confusion. Let me try a different explanation.

When you invoke foo(), you actually invoke this.foo(). Java simply lets you omit the this. In the example in the question, the type of this is SubClass.

So when Java executes the code in SuperClass.method1(), it eventually arrives at this.method2();

Using super doesn't change the instance pointed to by this. So the call goes to SubClass.method2() since this is of type SubClass.

Maybe it's easier to understand when you imagine that Java passes this as a hidden first parameter:

public class SuperClass
{
    public void method1(SuperClass this)
    {
        System.out.println("superclass method1");
        this.method2(this); // <--- this == mSubClass
    }

    public void method2(SuperClass this)
    {
        System.out.println("superclass method2");
    }

}

public class SubClass extends SuperClass
{
    @Override
    public void method1(SubClass this)
    {
        System.out.println("subclass method1");
        super.method1(this);
    }

    @Override
    public void method2(SubClass this)
    {
        System.out.println("subclass method2");
    }
}



public class Demo 
{
    public static void main(String[] args) 
    {
        SubClass mSubClass = new SubClass();
        mSubClass.method1(mSubClass);
    }
}

If you follow the call stack, you can see that this never changes, it's always the instance created in main().

Version 1:

// Update data of question values with $data from formulay
$Q1 = Question::find($id);
$Q1->fill($data);
$Q1->push();

Version 2:

$Q1 = Question::find($id);
$Q1->field = 'YOUR TEXT OR VALUE';
$Q1->save();

In case of answered question you can use them:

$page = Page::find($id);
$page2update = $page->where('image', $path);
$page2update->image = 'IMGVALUE';
$page2update->save();

To access services in two different namespaces you can use url like this:

HTTP://<your-service-name>.<namespace-with-that-service>.svc.cluster.local

To list out all your namespaces you can use:

kubectl get namespace

And for service in that namespace you can simply use:

kubectl get services -n <namespace-name>

this will help you.

Simple, make a simple asp page with the designer (just for the beginning) Lets say the body is something like this:

<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <br />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </div>
    <p>
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </p>
    </form>
</body>

Great, now every asp object IS an object. So you can access it in the asp's CS code. The asp's CS code is triggered by events (mostly). The class will probably inherit from System.Web.UI.Page

If you go to the cs file of the asp page, you'll see a protected void Page_Load(object sender, EventArgs e) ... That's the load event, you can use that to populate data into your objects when the page loads.

Now, go to the button in your designer (Button1) and look at its properties, you can design it, or add events from there. Just change to the events view, and create a method for the event.

The button is a web control Button Add a Click event to the button call it Button1Click:

void Button1Click(Object sender,EventArgs e) { }

Now when you click the button, this method will be called. Because ASP is object oriented, you can think of the page as the actual class, and the objects will hold the actual current data.

So if for example you want to access the text in TextBox1 you just need to call that object in the C# code:

String firstBox = TextBox1.Text;

In the same way you can populate the objects when event occur.

Now that you have the data the user posted in the textboxes , you can use regular C# SQL connections to add the data to your database.

Use , to separate strings and variables while printing:

print("If there was a birth every 7 seconds, there would be: ", births, "births")

, in print function separates the items by a single space:

>>> print("foo", "bar", "spam")
foo bar spam

or better use string formatting:

print("If there was a birth every 7 seconds, there would be: {} births".format(births))

String formatting is much more powerful and allows you to do some other things as well, like padding, fill, alignment, width, set precision, etc.

>>> print("{:d} {:03d} {:>20f}".format(1, 2, 1.1))
1 002             1.100000
  ^^^
  0's padded to 2

Demo:

>>> births = 4
>>> print("If there was a birth every 7 seconds, there would be: ", births, "births")
If there was a birth every 7 seconds, there would be:  4 births

# formatting
>>> print("If there was a birth every 7 seconds, there would be: {} births".format(births))
If there was a birth every 7 seconds, there would be: 4 births

char *name

You can change the char to which name points, and also the char at which it points.

const char* name

You can change the char to which name points, but you cannot modify the char at which it points.
correction: You can change the pointer, but not the char to which name points to (https://msdn.microsoft.com/en-us/library/vstudio/whkd4k6a(v=vs.100).aspx, see "Examples"). In this case, the const specifier applies to char, not the asterisk.

According to the MSDN page and http://en.cppreference.com/w/cpp/language/declarations, the const before the * is part of the decl-specifier sequence, while the const after * is part of the declarator.
A declaration specifier sequence can be followed by multiple declarators, which is why const char * c1, c2 declares c1 as const char * and c2 as const char.

EDIT:

From the comments, your question seems to be asking about the difference between the two declarations when the pointer points to a string literal.

In that case, you should not modify the char to which name points, as it could result in Undefined Behavior. String literals may be allocated in read only memory regions (implementation defined) and an user program should not modify it in anyway. Any attempt to do so results in Undefined Behavior.

So the only difference in that case (of usage with string literals) is that the second declaration gives you a slight advantage. Compilers will usually give you a warning in case you attempt to modify the string literal in the second case.

Online Sample Example:

#include <string.h>
int main()
{
    char *str1 = "string Literal";
    const char *str2 = "string Literal";
    char source[] = "Sample string";

    strcpy(str1,source);    //No warning or error, just Undefined Behavior
    strcpy(str2,source);    //Compiler issues a warning

    return 0;
}

Output:

cc1: warnings being treated as errors
prog.c: In function ‘main’:
prog.c:9: error: passing argument 1 of ‘strcpy’ discards qualifiers from pointer target type

Notice the compiler warns for the second case but not for the first.

DateTime.Now.ToShortTimeString().ToString()

This Will give you DateTime as 10:50PM

image has a shape of (64,64,3).

Your input placeholder _x have a shape of (?, 64,64,3).

The problem is that you're feeding the placeholder with a value of a different shape.

You have to feed it with a value of (1, 64, 64, 3) = a batch of 1 image.

Just reshape your image value to a batch with size one.

image = array(img).reshape(1, 64,64,3)

P.S: the fact that the input placeholder accepts a batch of images, means that you can run predicions for a batch of images in parallel. You can try to read more than 1 image (N images) and than build a batch of N image, using a tensor with shape (N, 64,64,3)

You can stash your local changes first, then pull, then pop the stash.

git stash
git pull origin master
git stash pop

Anything that overrides changes from remote will have conflicts which you will have to manually resolve.

To contribute, yesterday, PEZ's answer in this post, https://stackoverflow.com/a/431930/9710921 helped me to create an array to manage Excel columns for data exportations, like that:

public static function makeAlphas() : array {
    $alphas = $cells = range('A', 'Z');
    foreach($alphas as $alpha) {
        foreach($alphas as $beta) {
            $cells[] = $alpha.$beta;
        }
    }
    return $cells;
}

Thanks PEZ!

The garbage collector will come around and clean up anything that no longer has references to it. Unless you have unmanaged resources inside Foo, calling Dispose or using a using statement on it won't really help you much.

I'm fairly sure this applies, since it was still in C#. But, I took a game design course using XNA and we spent some time talking about the garbage collector for C#. Garbage collecting is expensive, since you have to check if you have any references to the object you want to collect. So, the GC tries to put this off as long as possible. So, as long as you weren't running out of physical memory when your program went to 700MB, it might just be the GC being lazy and not worrying about it yet.

But, if you just use Foo o outside the loop and create a o = new Foo() each time around, it should all work out fine.

I think, answers to this question are too old... currently some desktop and mobile browsers support HTML Templates for doing this.

I've built a little example:

Tested OK in Chrome 61.0, Opera 48.0, Opera Neon 1.0, Android Browser 6.0, Chrome Mobile 61.0 and Adblocker Browser 54.0
Tested KO in Safari 10.1, Firefox 56.0, Edge 38.14 and IE 11

If you have a Date (or Datetime) column, look at http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-format

 SELECT DATE_FORMAT(datecolumn,'%d/%m/%Y') FROM ...

Should do the job for MySQL, for SqlServer I'm sure there is an analog function. If you have a VARCHAR column, you might have at first to convert it to a date, see STR_TO_DATE for MySQL.

just run these commands

npm install
npm start

or

yarn start

Hope this will work for you thank you

Here is a really good way to manage this error. You can put the below line in .eslintrc.js file.

Based on the operating system, it will take appropriate line endings.

rules: {

Note: According to JDN96, the answer below may cause a memory leak by repeatedly destroying and recreating frames. However, I have not tested to verify this myself.

One way to switch frames in tkinter is to destroy the old frame then replace it with your new frame.

I have modified Bryan Oakley's answer to destroy the old frame before replacing it. As an added bonus, this eliminates the need for a container object and allows you to use any generic Frame class.

# Multi-frame tkinter application v2.3
import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self._frame = None
        self.switch_frame(StartPage)

    def switch_frame(self, frame_class):
        """Destroys current frame and replaces it with a new one."""
        new_frame = frame_class(self)
        if self._frame is not None:
            self._frame.destroy()
        self._frame = new_frame
        self._frame.pack()

class StartPage(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is the start page").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Open page one",
                  command=lambda: master.switch_frame(PageOne)).pack()
        tk.Button(self, text="Open page two",
                  command=lambda: master.switch_frame(PageTwo)).pack()

class PageOne(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is page one").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Return to start page",
                  command=lambda: master.switch_frame(StartPage)).pack()

class PageTwo(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is page two").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Return to start page",
                  command=lambda: master.switch_frame(StartPage)).pack()

if __name__ == "__main__":
    app = SampleApp()
    app.mainloop()

Explanation

switch_frame() works by accepting any Class object that implements Frame. The function then creates a new frame to replace the old one.

• Deletes old _frame if it exists, then replaces it with the new frame.
• Other frames added with .pack(), such as menubars, will be unaffected.
• Can be used with any class that implements tkinter.Frame.
• Window automatically resizes to fit new content

Version History

v2.3

- Pack buttons and labels as they are initialized

v2.2

- Initialize `_frame` as `None`.
- Check if `_frame` is `None` before calling `.destroy()`.

v2.1.1

- Remove type-hinting for backwards compatibility with Python 3.4.

v2.1

- Add type-hinting for `frame_class`.

v2.0

- Remove extraneous `container` frame.
    - Application now works with any generic `tkinter.frame` instance.
- Remove `controller` argument from frame classes.

PDOStatement->execute() can throw an exception

so what you can do is

try
{
PDOStatement->execute();
//record inserted
}
catch(Exception $e)
{
//Some error occured. (i.e. violation of constraints)
}

Your project supports .Net Framework 4.0 and .Net Framework 4.5. If you have upgrade issues

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

instead of can use;

ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

A static method can be called without an instance of the class. In your example you can call foo.bar2(), but not foo.bar(), because for bar you need an instance. Following code would work:

foo var = new ImplementsFoo();
var.bar();

If you call a static method, it will be executed always the same code. In the above example, even if you redefine bar2 in ImplementsFoo, a call to var.bar2() would execute foo.bar2().

If bar2 now has no implementation (that's what abstract means), you can call a method without implementation. That's very harmful.

If you want to find the rows that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)), create a logical index of (TRUE/FALSE) with (==). Use Reduce and OR (|) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums), double negate (!!) to get the rows with any matches.

indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)

Or vectorise and get the row indices with which with arr.ind=TRUE

indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
                                     arr.ind=TRUE)[,1])

Benchmarks

I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500 matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased

val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500, 
  replace=TRUE), ncol=500), stringsAsFactors=FALSE) 
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)

 konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
 akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
               na.rm=TRUE)}
 akrun2 <- function() {unique(which(Vectorize(function(x) x %in% 
              v1)(df1),arr.ind=TRUE)[,1])}


 library(microbenchmark)
 microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
 #Unit: relative
 #   expr       min         lq       mean     median         uq      max   neval

For ncol = 10, the results are slighjtly different:

You can use the :nth-child pseudo class like this:

.countTable table table td:nth-child(2)

Note though, this won't work in older browsers (or IE), you'll need to give the cells a class or use javascript in that case.

Adding http://minifiedjs.com/ to the list of answers :)

Code is similar to underscore and others:

var l123 = _.range(1, 4);      // same as _(1, 2, 3)
var l0123 = _.range(3);        // same as _(0, 1, 2)
var neg123 = _.range(-3, 0);   // same as _(-3, -2, -1)
var empty = _.range(2,1);      // same as _()

Docs here: http://minifiedjs.com/api/range.html

I use minified.js because it solves all my problems with low footprint and easy to understand syntax. For me, it is a replacement for jQuery, MustacheJS and Underscore/SugarJS in one framework.

Of course, it is not that popular as underscore. This might be a concern for some.

Here's a slightly different, but insightful take on why many features of C make sense: http://steve.yegge.googlepages.com/tour-de-babel#C

Basically, the standard CPU architecture is a Von Neumann architecture, and it's tremendously useful to be able to refer to the location of a data item in memory, and do arithmetic with it, on such a machine. If you know any variant of assembly language, you will quickly see how crucial this is at the low level.

C++ makes pointers a bit confusing, since it sometimes manages them for you and hides their effect in the form of "references." If you use straight C, the need for pointers is much more obvious: there's no other way to do call-by-reference, it's the best way to store a string, it's the best way to iterate through an array, etc.

Another option is using eval and parse, as in

d = 5
for (i in 1:10){
     eval(parse(text = paste('a', 1:10, ' = d + rnorm(3)', sep='')[i]))
}

It sounds like you're looking for applicationHost.config, which is located in C:\Windows\System32\inetsrv\config.

Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config and web.config.

find triggers on table:

select so.name, text
from sysobjects so, syscomments sc
where type = 'TR'
and so.id = sc.id
and text like '%TableName%'

and you can find store procedure which has reference of table:

SELECT Name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%yourtablename%'

There are no values that will cause the checkbox to be unchecked. If the checked attribute exists, the checkbox will be checked regardless of what value you set it to.

<input type="checkbox" checked />_x000D_
<input type="checkbox" checked="" />_x000D_
<input type="checkbox" checked="checked" />_x000D_
<input type="checkbox" checked="unchecked" />_x000D_
<input type="checkbox" checked="true" />_x000D_
<input type="checkbox" checked="false" />_x000D_

Renders everything checked in all modern browsers (FF3.6, Chrome 10, IE8).

When you use 'getResource' on a Class, a relative path is resolved based on the package the Class is in. When you use 'getResource' on a ClassLoader, a relative path is resolved based on the root folder.

If you use an absolute path, both 'getResource' methods will start at the root folder.

There are 2 differences:

2 methods creating a user and granting some privileges to him

create user userName identified by password;
grant connect to userName;

and

grant connect to userName identified by password;

do exactly the same. It creates a user and grants him the connect role.

different outcome

resource is a role in oracle, which gives you the right to create objects (tables, procedures, some more but no views!). ALL PRIVILEGES grants a lot more of system privileges.

To grant a user all privileges run you first snippet or

grant all privileges to userName identified by password;

You could also use realpath.

realpath(".") returns your document root.

You can call realpath with your specific path. Note that it will NOT work if the target folder or file does not exist. In such case it will return false, which could be useful for testing if a file exists.

In my case I needed to specify a path for a new file to be written to disk, and the solution was to append the path relative to document root:

$filepath = realpath(".") . "/path/to/newfile.txt";

Hope this helps anyone.

For me it was a big difference when I faced this scenario (here my story:)

I needed to extract text between tags and aggregate (by concat) the text including in innner tags.

/node() did the job, while /text() made half job

/text() only returned text not included in inner tags, because inner tags are not "text nodes". You may think, "just extract text included in the inner tags in an additional xpath", however, it becomes challenging to sort the text in this original order because you dont know where to place the aggregated text from the inner tags!because you dont know where to place the aggregated text from the inner nodes.

1. When U937 cells were infected with HIV-1,
2. no induction of NF-KB factor was detected
3. , whereas high level of progeny virions was produced,
4. suggesting that this factor was not required for viral replication
5. .

Finally, /node() did exactly what I wanted, because it gets the text from inner tags too.

With CSS Shapes you can go one step further than just float text around a rectangular image.

You can actually wrap text such that it takes the shape of the edge of the image or polygon that you are wrapping it around.

I just added custom headers to the Web.config and it worked like a charm.

On configuration - system.webServer:

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
  </customHeaders>
</httpProtocol>

I have the front end app and the backend on the same solution. For this to work, I need to set the web services project (Backend) as the default for this to work.

I was using ReST, haven't tried with anything else.

here are two samples: http://jsfiddle.net/H5q5h/1/

one uses float:left and a wrapper with overflow:hidden. the wrapper ensures the sibling of the wrapper starts below the wrapper.

the 2nd one uses the more recent display:inline-block and wrapper can be disregarded. but this is not generally supported by older browsers so tread lightly on this one. also, any white space between the items will cause an unnecessary "margin-like" white space on the left and right of the item divs.

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

My 2 cents:

If you are concatenating a significant amount of strings, you should be using the StringBuilder instead. IMO it's cleaner, and significantly faster.

For me, this works:

function transferAllStyles(elemFrom, elemTo)
{
  var prop;
  for (prop in elemFrom.style)
    if (typeof prop == "string")
      try { elemTo.style[prop] = elemFrom.style[prop]; }
      catch (ex) { /* don't care */ }
}

You could try using MultiMap instead of HashMap

Initialising it will require fewer lines of codes. Adding and retrieving the values will also make it shorter.

Map<String, List<Integer>> map = new HashMap<String, List<Integer>>();

would become:

Multimap<String, Integer> multiMap = ArrayListMultimap.create();

You can check this link: http://java.dzone.com/articles/hashmap-%E2%80%93-single-key-and

I got the same error since Application pool was stopped in IIS. After starting the App Pool, the issue was resolved.

Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group).

Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration"

I know this is an old question, but I just want to throw this out there that you can still use File.Create("filename")", just add .Dispose() to it.

File.Create("filename").Dispose();

This way it creates and closes the file for the next process to use it.

Using a union query will remove duplicates, and this is different than the behavior of full outer join that never removes any duplicate:

[Table: t1]                            [Table: t2]
value                                  value
-------                                -------
1                                      1
2                                      2
4                                      2
4                                      5

This is the expected result of full outer join:

value | value
------+-------
1     | 1
2     | 2
2     | 2
Null  | 5
4     | Null
4     | Null

This is the result of using left and right Join with union:

value | value
------+-------
Null  | 5 
1     | 1
2     | 2
4     | Null

[SQL Fiddle]

My suggested query is:

select 
    t1.value, t2.value
from t1 
left outer join t2  
  on t1.value = t2.value
union all      -- Using `union all` instead of `union`
select 
    t1.value, t2.value
from t2 
left outer join t1 
  on t1.value = t2.value
where 
    t1.value IS NULL 

Result of above query that is as same as expected result:

value | value
------+-------
1     | 1
2     | 2
2     | 2
4     | NULL
4     | NULL
NULL  | 5

@Steve Chambers: ^{[From comments, with many thanks!]}
Note: This may be the best solution, both for efficiency and for generating the same results as a FULL OUTER JOIN. This blog post also explains it well - to quote from Method 2: "This handles duplicate rows correctly and doesn’t include anything it shouldn’t. It’s necessary to use UNION ALL instead of plain UNION, which would eliminate the duplicates I want to keep. This may be significantly more efficient on large result sets, since there’s no need to sort and remove duplicates."

I decided to add another solution that comes from full outer join visualization and math, it is not better that above but more readable:

Full outer join means (t1 ? t2): all in t1 or in t2
(t1 ? t2) = (t1 n t2) + t1_only + t2_only: all in both t1 and t2 plus all in t1 that aren't in t2 and plus all in t2 that aren't in t1:

-- (t1 n t2): all in both t1 and t2
select t1.value, t2.value
from t1 join t2 on t1.value = t2.value    
union all  -- And plus 
-- all in t1 that not exists in t2
select t1.value, null
from t1
where not exists( select 1 from t2 where t2.value = t1.value)    
union all  -- and plus
-- all in t2 that not exists in t1
select null, t2.value
from t2
where not exists( select 1 from t1 where t2.value = t1.value)

UPDATE Table SET Column = REPLACE(Column, char(9), '')

(\d+)\s+(\(.*?\))?\s?Z

Note the escaped parentheses, and the ? (zero or once) quantifiers. Any of the groups you don't want to capture can be (?: non-capture groups).

I agree about the spaces. \s is a better option there. I also changed the quantifier to insure there are digits at the beginning. As far as newlines, that would depend on context: if the file is parsed line by line it won't be a problem. Another option is to anchor the start and end of the line (add a ^ at the front and a $ at the end).

Don't use str() method directly in html instead use with y=x|string()

<div class="row">
    {% for x in range(photo_upload_count) %}
        {% with y=x|string() %}

    <div col-md-4 >
        <div class="col-md-12">
            <div class="card card-primary "  style="border:1px solid #000">
                <div class="card-body">
                    {% if data['profile_photo']!= None: %}
                        <img class="profile-user-img img-responsive" src="{{ data['photo_'+y] }}" width="200px" alt="User profile picture">
                    {% else: %}
                        <img class="profile-user-img img-responsive" src="static/img/user.png" width="200px" alt="User profile picture">
                    {% endif %}
                </div>
                <div class="card-footer text-center">
                    <a href="{{value}}edit_photo/{{ 'photo_'+y }}" class="btn btn-primary">Edit</a>
                </div>
            </div>
        </div>
    </div>
    {% endwith %}
    {% endfor %}
</div>

I also needed build-essential installed:

sudo apt-get install build-essential

I encountered this error when I was trying to create a DialogBox when some action is taken inside the CustomAdapter class. This was not an Activity but an Adapter class. After 36 hrs of efforts and looking up for solutions, I came up with this.

Send the Activity as a parameter while calling the CustomAdapter.

CustomAdapter ca = new CustomAdapter(MyActivity.this,getApplicationContext(),records);

Define the variables in the custom Adapter.

Activity parentActivity;
Context context;

Call the constructor like this.

public CustomAdapter(Activity parentActivity,Context context,List<Record> records){
    this.parentActivity=parentActivity;
    this.context=context;
    this.records=records;
}

And finally when creating the dialog box inside the adapter class, do it like this.

AlertDialog ad = new AlertDialog.Builder(parentActivity).setTitle("Your title");

and so on..

I hope this helps you

You need to add a subview to the first window with the UITextEffectsWindow type. To the first, because custom keyboards add their UITextEffectsWindow, and if you add a subview to it this won't work correctly. Also, you cannot add a subview to the last window because the keyboard, for example, is also a window and you can`t present from the keyboard window. So the best solution I found is to add subview (or even push view controller) to the first window with UITextEffectsWindow type, this window covers accessory view, navbar - everything.

let myView = MyView()
myView.frame = UIScreen.main.bounds

guard let textEffectsWindow = NSClassFromString("UITextEffectsWindow") else { return }
let window = UIApplication.shared.windows.first { window in
    window.isKind(of: textEffectsWindow)
}
window?.rootViewController?.view.addSubview(myView)

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   78445dd45222: Pull complete
   Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash
   
   Share images, automate workflows, and more with a free Docker ID:

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

The basic difference :

Linear regression is basically a regression model which means its will give a non discreet/continuous output of a function. So this approach gives the value. For example : given x what is f(x)

For example given a training set of different factors and the price of a property after training we can provide the required factors to determine what will be the property price.

Logistic regression is basically a binary classification algorithm which means that here there will be discreet valued output for the function . For example : for a given x if f(x)>threshold classify it to be 1 else classify it to be 0.

For example given a set of brain tumour size as training data we can use the size as input to determine whether its a benine or malignant tumour. Therefore here the output is discreet either 0 or 1.

*here the function is basically the hypothesis function

use:

my_function({width:12});

Instead of:

my_function(width:12);

After reading the above answers, here adding my interpretations.

Suppose browsing online, web browser is your frame which decides where and how big to show webpage. Scroller of browser is your bounds.origin that decides which part of webpage will be shown. bounds.origin is hard to understand. The best way to learn is creating Single View Application, trying modify these parameters and see how subviews change.

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(100.0f, 200.0f, 200.0f, 400.0f)];
[view1 setBackgroundColor:[UIColor redColor]];

UIView *view2 = [[UIView alloc] initWithFrame:CGRectInset(view1.bounds, 20.0f, 20.0f)];
[view2 setBackgroundColor:[UIColor yellowColor]];
[view1 addSubview:view2];

[[self view] addSubview:view1];

NSLog(@"Old view1 frame %@, bounds %@, center %@", NSStringFromCGRect(view1.frame), NSStringFromCGRect(view1.bounds), NSStringFromCGPoint(view1.center));
NSLog(@"Old view2 frame %@, bounds %@, center %@", NSStringFromCGRect(view2.frame), NSStringFromCGRect(view2.bounds), NSStringFromCGPoint(view2.center));

// Modify this part.
CGRect bounds = view1.bounds;
bounds.origin.x += 10.0f;
bounds.origin.y += 10.0f;

// incase you need width, height
//bounds.size.height += 20.0f;
//bounds.size.width += 20.0f;

view1.bounds = bounds;

NSLog(@"New view1 frame %@, bounds %@, center %@", NSStringFromCGRect(view1.frame), NSStringFromCGRect(view1.bounds), NSStringFromCGPoint(view1.center));
NSLog(@"New view2 frame %@, bounds %@, center %@", NSStringFromCGRect(view2.frame), NSStringFromCGRect(view2.bounds), NSStringFromCGPoint(view2.center));

As you have it, the argument w is expecting a value after -w on the command line. If you are just looking to flip a switch by setting a variable True or False, have a look here (specifically store_true and store_false)

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('-w', action='store_true')

where action='store_true' implies default=False.

Conversely, you could haveaction='store_false', which implies default=True.

In your code, you can find this function:

// Update a particular HTML element with a new value
function updateHTML(elmId, value) {
  document.getElementById(elmId).innerHTML = value;
}

Later on, you call this function with several params:

updateHTML("videoCurrentTime", secondsToHms(ytplayer.getCurrentTime())+' /');
updateHTML("videoDuration", secondsToHms(ytplayer.getDuration()));
updateHTML("bytesTotal", ytplayer.getVideoBytesTotal());
updateHTML("startBytes", ytplayer.getVideoStartBytes());
updateHTML("bytesLoaded", ytplayer.getVideoBytesLoaded());
updateHTML("volume", ytplayer.getVolume());

The first param is used for the "getElementById", but the elements with ID "bytesTotal", "startBytes", "bytesLoaded" and "volume" don't exist. You'll need to create them, since they'll return null.

Parse the two dates firstDate and secondDate using SimpleDateFormat.

firstDate.after(secondDate);

firstDate.before(secondDate);

Try this for compatibility;

<script type="text/javascript">
        $(function() {
            setTimeout(function() {
                window.location.href = $('#myAnchor').attr("href");

            }, 1500);
        });
    </script>

you dont need to change your JSON format.

replace:

console.log(data.phones.length);

with:

console.log( Object.keys( data.phones ).length ) ;

Suppose current url = sub.example.com

    $host = array_reverse(explode('.', $_SERVER['SERVER_NAME']));

    if (count($host) >= 3){
       echo "Main domain is = ".$host[1].".".$host[0]." & subdomain is = ".$host[2];
       // Main domain is = example.com & subdomain is = sub
    } else {
       echo "Main domain is = ".$host[1].".".$host[0]." & subdomain not found";
       // "Main domain is = example.com & subdomain not found";
    }

Theres a setting max_input_time (on Apache) for many webservers that defines how long they will wait for post data, regardless of the size. If this time runs out the connection is closed without even touching the php.

So your problem is not necessarily solvable with php only but you will need to change the server settings too.

Try something like this:

$link = @new mysqli($this->host, $this->user, $this->pass)
$statement = $link->prepare($sqlStatement);
                if(!$statement)
                {
                    $this->debug_mode('query', 'error', '#Query Failed<br/>' . $link->error);
                    return false;
                }

I got this error because I pasted alias columns into a DECLARE statement.

DECLARE @userdata TABLE(
f.TABLE_CATALOG nvarchar(100),
f.TABLE_NAME nvarchar(100),
f.COLUMN_NAME nvarchar(100),
p.COLUMN_NAME nvarchar(100)
)
SELECT * FROM @userdata

SELECT * FROM @userdata

NO ERROR

Ngrok can be installed with Yarn , then you can run by power Sheel. it's was the only way that worked for me in windows 10 . In the begin you need to install the Node : https://nodejs.org/en/. and the yarn: https://nodejs.org/en/.

The row_number() function would be the best approach to this problem.

UPDATE T
    SET T.Number = R.rowNum
    FROM Test T
    JOIN (
        SELECT T2.id,row_number() over (order by T2.Id desc) rowNum from Test T2
    ) R on T.id=R.id 

The usual method is to use the NEWID() function, which generates a unique GUID. So,

SELECT * FROM dbo.Foo ORDER BY NEWID();

As this is the first result on google and there's no C++20 answer yet, here's how to use std::chrono to do this:

#include <chrono>

//...

using namespace std::chrono;
int64_t timestamp = duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();

In versions of C++ before 20, system_clock's epoch being Unix epoch is a de-facto convention, but it's not standardized. If you're not on C++20, use at your own risk.

Here's a short and sweet JavaScript function to fetch the session ID:

function session_id() {
    return /SESS\w*ID=([^;]+)/i.test(document.cookie) ? RegExp.$1 : false;
}

Or if you prefer a variable, here's a simple one-liner:

var session_id = /SESS\w*ID=([^;]+)/i.test(document.cookie) ? RegExp.$1 : false;

Should match the session ID cookie for PHP, JSP, .NET, and I suppose various other server-side processors as well.

I got this error message when I entered a number (999999) that was out of the range I'd set for the form.

<input type="number" ng-model="clipInMovieModel" id="clipInMovie" min="1" max="10000">

Not in stock Windows but it is provided by Services for Unix and there are several simple batch scripts floating around that accomplish the same thing such this this one.

Another way of doing this is to use ravel

model = forest.fit(train_fold, train_y.values.reshape(-1,))

The solution I came up with was to use the publishing feature.

File > Publish to the web...

Then in the URL you can just replace the .../edit path with .../pub

This solves the problem described in the question of breaking up a table with footnotes.

To expand on Johan's answer, if the part_num column in the sub-select can contain null values then the query will break.

To correct this, add a null check...

SELECT pm.id FROM r2r.partmaster pm
WHERE pm.id NOT IN 
      (SELECT pd.part_num FROM wpsapi4.product_details pd 
                  where pd.part_num is not null)

• Sorry but I couldn't add a comment as I don't have the rep!

This method handles spaces well.

files="$(find -L "$dir" -type f)"
echo "Count: $(echo -n "$files" | wc -l)"
echo "$files" | while read file; do
  echo "$file"
done

Edit, fixes off-by-one

function count() {
    files="$(find -L "$1" -type f)";
    if [[ "$files" == "" ]]; then
        echo "No files";
        return 0;
    fi
    file_count=$(echo "$files" | wc -l)
    echo "Count: $file_count"
    echo "$files" | while read file; do
        echo "$file"
    done
}

function invertSign($value)
{
    return -$value;
}

Import DatePipe from angular/common and then use the below code:

var datePipe = new DatePipe();
    this.setDob = datePipe.transform(userdate, 'dd/MM/yyyy');

where userdate will be your date string. See if this helps.

Make note of the lowercase for date and year :

d- date
M- month
y-year

EDIT

You have to pass locale string as an argument to DatePipe, in latest angular. I have tested in angular 4.x

For Example:

var datePipe = new DatePipe('en-US');

Either of the latter two, since val could potentially be of a type that defines __eq__() to return true when passed None.

For those it might help, I use this list as a reference to define my content-type when I have to deal with images on my app.

It says that jpg extension can be declared with Content-type : image/jpeg

There isn't any image/jpg attribute for content-type.

I was facing the same issue.The dtypes of y_test and y_pred were different. Make sure that the dtypes are same for both.

If "mysqld" IS running, it's possible your data is corrupted. Try running this:

mysqld

Read through the wall of data, and check if mysqld is reporting that the database is corrupted. Corruption can present in many unintuitive ways:

• mysql -uroot returns "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)".
• mysql.server start returns "ERROR! The server quit without updating PID".
• Sequel Pro and MySQL Workbench responds that they can't connect to MySQL on localhost or 127.0.0.1.

To recover your data, open my.cnf and add the following line in the [mysqld] section:

innodb_force_recovery=1

Restart mysqld:

$ brew services restart [email protected]

Now you can connect to it, but it’s in limited read-only mode.

If you're using InnoDB, run this to export all your data:

$ mysqldump -u root -p --all-databases --add-drop-database --add-drop-table > data-recovery.sql

The file is created in your ~ dir. It may take some time.

Once finished, remove innodb_force_recovery=1 from my.cnf, then restart mysql in normal mode:

$ brew services restart [email protected]

Drop all the databases. I did this using Sequel Pro. This deletes all your original data. Make sure your data-recovery.sql looks good before doing this. Also consider backing up /usr/local/var/mysql to be extra careful.

Then restore the databases, tables, and data with this:

$ mysql -uroot < ~/data-recovery.sql

This can be a long import/restoration process. Once complete, you’re good to go!

Thanks go to https://severalnines.com/database-blog/my-mysql-database-corrupted-what-do-i-do-now for the recovery instructions. The link has further instructions on MyISAM recovery.

I am on MacOS, and the most convenient way for me is to using CyberDuck, which is free (also available for Windows). You can connect to your remote SSH file system and edit your file using your local editor. What CyberDuck does is download the file to a temporary place on your local OS and open it with your editor. Once you save the file, CyberDuck automatically upload it to your remote system. It seems transparent as if you are editing your remote file using your local editor. The developers of Cyberduck also make MountainDuck for mounting remote files systems.

I had a task on BE side to find all entities from a repo, and to add a new property url and to return to controller layer. This is how I achieved it (thanks to Ajedi32's response):

async findAll(): Promise<ImageResponse[]> {
    const images = await this.imageRepository.find(); // This is an array of type Image (DB entity)
    const host = this.request.get('host');
    const mappedImages = await Promise.all(images.map(image => ({...image, url: `http://${host}/images/${image.id}`}))); // This is an array of type Object
    return plainToClass(ImageResponse, mappedImages); // Result is an array of type ImageResponse
  }

Note: Image (entity) doesn't have property url, but ImageResponse - has

I had a similar issue , The function name i was using matched one of the inbuilt functions declared in one of the header files that i included in the program.Reading through the compiler error message will tell you the exact header file and function name.Changing the function name solved this issue for me

I'm assuming this is happening for an anonymous class. When you create an anonymous class you actually create a class that extends the class whose name you got.

The "cleaner" way to get the name you want is:

If your class is an anonymous inner class, getSuperClass() should give you the class that it was created from. If you created it from an interface than you're sort of SOL because the best you can do is getInterfaces() which might give you more than one interface.

The "hacky" way is to just get the name with getClassName() and use a regex to drop the $1.

You should be able to do something like this:

byte[] bitmap = GetYourImage();

using(Image image = Image.FromStream(new MemoryStream(bitmap)))
{
    image.Save("output.jpg", ImageFormat.Jpeg);  // Or Png
}

Look here for more info.

Hopefully this helps.

You can force the toolbar by wrapping title and level right padding which has default left padding for title. Than put background color to the parent of toolbar and that way part which is cut out by wrapping title is in the same color(white in my example):

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/white">

        <android.support.v7.widget.Toolbar
           android:id="@+id/toolbar"
           android:layout_width="wrap_content"
           android:layout_height="56dp"
           android:layout_gravity="center_horizontal"
           android:paddingEnd="15dp"
           android:paddingRight="15dp"
           android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
           app:titleTextColor="@color/black"/>

</android.support.design.widget.AppBarLayout>

You can make use of

display: flex;
align-items: center;
justify-content: center;

on your parent component

I believe that is is a move operator. operator= is the assignment operator, say vector x = vector y. The clear() function call sounds like as if it is deleting the contents of the vector to prevent a memory leak. The operator returns a pointer to the new vector.

This way,

std::vector<int> a(100, 10);
std::vector<int> b = a;
for(unsigned int i = 0; i < b.size(); i++)
{
    std::cout << b[i] << ' ';
}

Even though we gave vector a values, vector b has the values. It's the magic of the operator=()!

MSDN -- How to create a move constructor

Try:

[self.view endEditing:YES];

ImageView img = (ImageView) findViewById(R.id.myImageId);
img.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
       // your code here
    }
});

You can get the last char like this :

var lastChar=yourString.charAt(yourString.length-1);

• Irmin
• Flur.ee
• Crux DB
• TerminusDB

I have been looking for the same feature for Postgres (or SQL databases in general) for a while, but I found no tools to be suitable (simple and intuitive) enough. This is probably due to the binary nature of how data is stored. Klonio sounds ideal but looks dead. Noms DB looks interesting (and alive). Also take a look at Irmin (OCaml-based with Git-properties).

Though this doesn't answer the question in that it would work with Postgres, check out the Flur.ee database. It has a "time-travel" feature that allows you to query the data from an arbitrary point in time. I'm guessing it should be able to work with a "branching" model.

This database was recently being developed for blockchain-purposes. Due to the nature of blockchains, the data needs to be recorded in increments, which is exactly how git works. They are targeting an open-source release in Q2 2019.

Because each Fluree database is a blockchain, it stores the entire history of every transaction performed. This is part of how a blockchain ensures that information is immutable and secure.

Update: Also check out the Crux database, which can query across the time dimension of inserts, which you could see as 'versions'. Crux seems to be an open-source implementation of the highly appraised Datomic.

Crux is a bitemporal database that stores transaction time and valid time histories. While a [uni]temporal database enables "time travel" querying through the transactional sequence of database states from the moment of database creation to its current state, Crux also provides "time travel" querying for a discrete valid time axis without unnecessary design complexity or performance impact. This means a Crux user can populate the database with past and future information regardless of the order in which the information arrives, and make corrections to past recordings to build an ever-improving temporal model of a given domain.

Update II Check out Terminus DB: "Documentation for TerminusDB - an open-source graph database that stores data like git".

I'm posting this here as I am sure more people will be comeing across this issue. I installed Security Update for microsoft Visual Studio 2010 Service Pack 1 (KB2565057) and lost Intellisense in SQL Server Management studio 2008 (not R2).

An uninstall of the SP restored Intellisense .. Don't you just love Microsoft????

Unfortunately, I don't think Pandas allows one to drop dups off the indices. I would suggest the following:

df3 = df3.reset_index() # makes date column part of your data
df3.columns = ['timestamp','A','B','rownum'] # set names
df3 = df3.drop_duplicates('timestamp',take_last=True).set_index('timestamp') #done!

If you're using Python 3 then you must install as follows:

sudo apt-get update
sudo apt-get install python3-tk

Tkinter for Python 2 (python-tk) is different from Python 3's (python3-tk).

Try this namespaces module

namespaceModuleFile.ts

export namespace Bookname{
export class Snows{
    name:any;
    constructor(bookname){
        console.log(bookname);
    }
}
export class Adventure{
    name:any;
    constructor(bookname){
        console.log(bookname);
    }
}
}





export namespace TreeList{
export class MangoTree{
    name:any;
    constructor(treeName){
        console.log(treeName);
    }
}
export class GuvavaTree{
    name:any;
    constructor(treeName){
        console.log(treeName);
    }
}
}

bookTreeCombine.ts

---compilation part---

import {Bookname , TreeList} from './namespaceModule';
import b = require('./namespaceModule');
let BooknameLists = new Bookname.Adventure('Pirate treasure');
BooknameLists = new Bookname.Snows('ways to write a book'); 
const TreeLis = new TreeList.MangoTree('trees present in nature');
const TreeLists = new TreeList.GuvavaTree('trees are the celebraties');

I'm assuming that when you say 'click the button, it moves to the top a little' you're talking about the mouse down click state for the button, and that when you release the mouse click, it returns to its normal state? And that you're disabling the default rendering of the button by using:

input, button, submit { border:none; } 

If so..

Personally, I've found that you can't actually stop/override/disable this IE native action, which led me to change my markup a little to allow for this movement and not affect the overall look of the button for the various states.

This is my final mark-up:

<span class="your-button-class">_x000D_
    <span>_x000D_
        <input type="Submit" value="View Person">_x000D_
    </span>_x000D_
</span>

Yes. You can get an element by its ID by calling document.getElementById. It will return an element node if found, and null otherwise:

var x = document.getElementById("elementid");   // Get the element with id="elementid"
x.style.color = "green";                        // Change the color of the element

I seem to be having success doing

org.jboss.logmanager.Logger logger = org.jboss.logmanager.Logger.getLogger("");
logger.setLevel(java.util.logging.Level.ALL);

Then to get detailed logging from netty, the following has done it

org.slf4j.impl.SimpleLogger.setLevel(org.slf4j.impl.SimpleLogger.TRACE);

There are several good answers on here but I wanted to add one since it may be helpful for users like me who have Tomcat installed as a service on a Windows machine.

Option 3 here: http://www.codejava.net/servers/tomcat/4-ways-to-change-jre-for-tomcat

Basically, open tomcatw.exe and point Tomcat to the version of the JVM you need to use then restart the service. Ensure your deployed applications still work as well.

Use Math.Max:

int x = 3, y = 4, z = 5;
Console.WriteLine(Math.Max(Math.Max(x, y), z));

It would be great if you use :hover pseudo class over the onmouseover event

td:hover
{
   background-color:white
}

and for the default styling just use

td
{
  background-color:black
}

As you want to use these styling not over all the td elements then you need to specify the class to those elements and add styling to that class like this

.customTD
{
   background-color:black
}
.customTD:hover
{
  background-color:white;
}

You can also use :nth-child selector to select the td elements

Just to update these answers, ESRI has included this tool, known as Layer to KML in ArcMap 10.X. Also, a Map to KML tool exists.

Simply import the desired layer (vector or raster) and choose the output location, resolution, etc. Very simple tool.

The above solutions didn't work for me. Here is what I finally came up with:

$( "#ddl" ).find( "option:selected" ).text();           // Text
$( "#ddl" ).find( "option:selected" ).prop("value");    // Value

You can simply use the SASS mixin to change the number of cards across in each breakpoint / grid tier.

.card-columns {
  @include media-breakpoint-only(xl) {
    column-count: 5;
  }
  @include media-breakpoint-only(lg) {
    column-count: 4;
  }
  @include media-breakpoint-only(md) {
    column-count: 3;
  }
  @include media-breakpoint-only(sm) {
    column-count: 2;
  }
}

SASS Demo: http://www.codeply.com/go/FPBCQ7sOjX

Or, CSS only like this...

@media (min-width: 576px) {
    .card-columns {
        column-count: 2;
    }
}

@media (min-width: 768px) {
    .card-columns {
        column-count: 3;
    }
}

@media (min-width: 992px) {
    .card-columns {
        column-count: 4;
    }
}

@media (min-width: 1200px) {
    .card-columns {
        column-count: 5;
    }
}

Just use append:

list1 = [1, 2, 3, 4, 5]
list2 = [123, 234, 456]
d = {'a': [], 'b': []}
d['a'].append(list1)
d['a'].append(list2)
print d['a']

try this:

a = new Array();
a.push(10);
a.push(60);
a.push(20);
a.push(30);
a.push(100);
a.sort(Test)

document.write(a);


function Test(a,b)
{
    return a > b ? true : false;
}

If the goal is to be able to push to a GitHub repo whenever you want to, then in Windows under C:\Users\tiago\.ssh where the keys are stored (at least in my case), create a file named config and add the following in it

Host github.com
    HostName github.com
    User your_user_name
    IdentityFile ~/.ssh/your_file_name

Then simply open Git Bash and you'll be able to push without having to manually start the ssh-agent and adding the key.

Your proposed doCalculationsAndUpdateUIs does data processing and dispatches UI updates to the main queue. I presume that you have dispatched doCalculationsAndUpdateUIs to a background queue when you first called it.

While technically fine, that's a little fragile, contingent upon your remembering to dispatch it to the background every time you call it: I would, instead, suggest that you do your dispatch to the background and dispatch back to the main queue from within the same method, as it makes the logic unambiguous and more robust, etc.

Thus it might look like:

- (void)doCalculationsAndUpdateUIs {

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, NULL), ^{

        // DATA PROCESSING 1 

        dispatch_async(dispatch_get_main_queue(), ^{
            // UI UPDATION 1
        });

        /* I expect the control to come here after UI UPDATION 1 */

        // DATA PROCESSING 2

        dispatch_async(dispatch_get_main_queue(), ^{
            // UI UPDATION 2
        });

        /* I expect the control to come here after UI UPDATION 2 */

        // DATA PROCESSING 3

        dispatch_async(dispatch_get_main_queue(), ^{
            // UI UPDATION 3
        });
    });
}

In terms of whether you dispatch your UI updates asynchronously with dispatch_async (where the background process will not wait for the UI update) or synchronously with dispatch_sync (where it will wait for the UI update), the question is why would you want to do it synchronously: Do you really want to slow down the background process as it waits for the UI update, or would you like the background process to carry on while the UI update takes place.

Generally you would dispatch the UI update asynchronously with dispatch_async as you've used in your original question. Yes, there certainly are special circumstances where you need to dispatch code synchronously (e.g. you're synchronizing the updates to some class property by performing all updates to it on the main queue), but more often than not, you just dispatch the UI update asynchronously and carry on. Dispatching code synchronously can cause problems (e.g. deadlocks) if done sloppily, so my general counsel is that you should probably only dispatch UI updates synchronously if there is some compelling need to do so, otherwise you should design your solution so you can dispatch them asynchronously.

In answer to your question as to whether this is the "best way to achieve this", it's hard for us to say without knowing more about the business problem being solved. For example, if you might be calling this doCalculationsAndUpdateUIs multiple times, I might be inclined to use my own serial queue rather than a concurrent global queue, in order to ensure that these don't step over each other. Or if you might need the ability to cancel this doCalculationsAndUpdateUIs when the user dismisses the scene or calls the method again, then I might be inclined to use a operation queue which offers cancelation capabilities. It depends entirely upon what you're trying to achieve.

But, in general, the pattern of asynchronously dispatching a complicated task to a background queue and then asynchronously dispatching the UI update back to the main queue is very common.

You could always do

if (str == null || str.equals(null))

This will first check the object reference and then check the object itself providing the reference isnt null.

You can also do it on the worksheet level captured in the worksheet's change event. If that suites your needs better. Allows for dynamic locking based on values, criteria, ect...

Private Sub Worksheet_Change(ByVal Target As Range)

    'set your criteria here
    If Target.Column = 1 Then

        'must disable events if you change the sheet as it will
        'continually trigger the change event
        Application.EnableEvents = False
        Application.Undo
        Application.EnableEvents = True

        MsgBox "You cannot do that!"
    End If
End Sub

There are a lot of answers here, but I'll add my approach since I found this post while working on the same problem.

Starting with what we know here are the number from 0 to 16.

Number           encoded in bits         minimum number of bits to encode
0                000000                  1
1                000001                  1
2                000010                  2
3                000011                  2
4                000100                  3
5                000101                  3
6                000110                  3
7                000111                  3
8                001000                  4
9                001001                  4
10               001010                  4
11               001011                  4
12               001100                  4
13               001101                  4
14               001110                  4
15               001111                  4
16               010000                  5

looking at the breaks, it shows this table

number <=       number of bits
1               0
3               2
7               3
15              4

So, now how do we compute the pattern?

Remember that log base 2 (n) = log base 10 (n) / log base 10 (2)

number    logb10 (n)   logb2 (n)   ceil[logb2(n)] 
1         0            0           0           (special case)
3         0.477        1.58        2
7         0.845        2.807       3  
8         0.903        3           3           (special case)
15        1.176        3.91        4
16        1.204        4           4           (special case)
31        1.491        4.95        5
63        1.799        5.98        6

Now the desired result matching the first table. Notice how also some values are special cases. 0 and any number which is a powers of 2. These values dont change when you apply ceiling so you know you need to add 1 to get the minimum bit field length.

To account for the special cases add one to the input. The resulting code implemented in python is:

from math import log
from math import ceil
def min_num_bits_to_encode_number(a_number):
    a_number=a_number+1  # adjust by 1 for special cases

    # log of zero is undefined
    if 0==a_number:
        return 0
    num_bits = int(ceil(log(a_number,2)))  # logbase2 is available
    return (num_bits)

I faced similar issue with Spring MVC application. I used < mvc:resources > tag to resolve this issue.

If you don't like to import the full apache.commons, I've extracted the same functionality:

public class StringUtils {
    public static String getBaseName(String filename) {
        return removeExtension(getName(filename));
    }

    public static int indexOfLastSeparator(String filename) {
        if(filename == null) {
            return -1;
        } else {
            int lastUnixPos = filename.lastIndexOf(47);
            int lastWindowsPos = filename.lastIndexOf(92);
            return Math.max(lastUnixPos, lastWindowsPos);
        }
    }

    public static String getName(String filename) {
        if(filename == null) {
            return null;
        } else {
            int index = indexOfLastSeparator(filename);
            return filename.substring(index + 1);
        }
    }

    public static String removeExtension(String filename) {
        if(filename == null) {
            return null;
        } else {
            int index = indexOfExtension(filename);
            return index == -1?filename:filename.substring(0, index);
        }
    }

    public static int indexOfExtension(String filename) {
        if(filename == null) {
            return -1;
        } else {
            int extensionPos = filename.lastIndexOf(46);
            int lastSeparator = indexOfLastSeparator(filename);
            return lastSeparator > extensionPos?-1:extensionPos;
        }
    }
}

You need to remove the / before the [. Predicates (the parts in [ ]) shouldn't have slashes immediately before them. Also, to select the Employee element itself, you should leave off the /text() at the end or otherwise you'd just be selecting the whitespace text values immediately under the Employee element.

//Employee[@id='4']

Edit: As Jens points out in the comments, // can be very slow because it searches the entire document for matching nodes. If the structure of the documents you're working with is going to be consistent, you are probably best off using a full path, for example:

/Employees/Employee[@id='4']

Scott Jehl came up with a fantastic solution that uses the accelerometer to anticipate orientation changes. This solution is very responsive and does not interfere with zoom gestures.

https://github.com/scottjehl/iOS-Orientationchange-Fix

How it works: This fix works by listening to the device's accelerometer to predict when an orientation change is about to occur. When it deems an orientation change imminent, the script disables user zooming, allowing the orientation change to occur properly, with zooming disabled. The script restores zoom again once the device is either oriented close to upright, or after its orientation has changed. This way, user zooming is never disabled while the page is in use.

Minified source:

/*! A fix for the iOS orientationchange zoom bug. Script by @scottjehl, rebound by @wilto.MIT License.*/(function(m){if(!(/iPhone|iPad|iPod/.test(navigator.platform)&&navigator.userAgent.indexOf("AppleWebKit")>-1)){return}var l=m.document;if(!l.querySelector){return}var n=l.querySelector("meta[name=viewport]"),a=n&&n.getAttribute("content"),k=a+",maximum-scale=1",d=a+",maximum-scale=10",g=true,j,i,h,c;if(!n){return}function f(){n.setAttribute("content",d);g=true}function b(){n.setAttribute("content",k);g=false}function e(o){c=o.accelerationIncludingGravity;j=Math.abs(c.x);i=Math.abs(c.y);h=Math.abs(c.z);if(!m.orientation&&(j>7||((h>6&&i<8||h<8&&i>6)&&j>5))){if(g){b()}}else{if(!g){f()}}}m.addEventListener("orientationchange",f,false);m.addEventListener("devicemotion",e,false)})(this);

Swift's String type does not provide a characterAtIndex method because there are several ways a Unicode string could be encoded. Are you going with UTF8, UTF16, or something else?

You can access the CodeUnit collections by retrieving the String.utf8 and String.utf16 properties. You can also access the UnicodeScalar collection by retrieving the String.unicodeScalars property.

In the spirit of NSString's implementation, I'm returning a unichar type.

extension String
{
    func characterAtIndex(index:Int) -> unichar
    {
        return self.utf16[index]
    }

    // Allows us to use String[index] notation
    subscript(index:Int) -> unichar
    {
        return characterAtIndex(index)
    }
}

let text = "Hello Swift!"
let firstChar = text[0]

As others have noted, it is usually preferable to specify a minimum logging level to log that level and any others more severe than it. It seems like you are just thinking about the logging levels backwards.

However, if you want more fine-grained control over logging individual levels, you can tell log4net to log only one or more specific levels using the following syntax:

<filter type="log4net.Filter.LevelMatchFilter">
  <levelToMatch value="WARN"/>
</filter>

Or to exclude a specific logging level by adding a "deny" node to the filter.

You can stack multiple filters together to specify multiple levels. For instance, if you wanted only WARN and FATAL levels. If the levels you wanted were consecutive, then the LevelRangeFilter is more appropriate.

Reference Doc: log4net.Filter.LevelMatchFilter

If the other answers haven't given you enough information, hopefully this will help you get what you want out of log4net.

Simply add $autoload['helper'] = array('url'); to autoload.php.

Like this:

var root = document.getElementsByTagName( 'html' )[0]; // '0' to assign the first (and only `HTML` tag)

root.setAttribute( 'class', 'myCssClass' );

Or use this as your 'setter' line to preserve any previously applied classes: (thanks @ama2)

root.className += ' myCssClass';

Or, depending on the required browser support, you can use the classList.add() method:

root.classList.add('myCssClass');

https://developer.mozilla.org/en-US/docs/Web/API/Element/classList http://caniuse.com/#feat=classlist

UPDATE:

A more elegant solution for referencing the HTML element might be this:

var root = document.documentElement;
root.className += ' myCssClass';
// ... or:
//  root.classList.add('myCssClass');
//

Its absolutely possible only when you set layer.masksToBounds = true and do you rest stuff.

As mentioned in one of the other answers, you can use putc(int c, FILE *stream), putchar(int c) or fputc(int c, FILE *stream) for this purpose.

What's important to note is that using any of the above functions is from some to signicantly faster than using any of the format-parsing functions like printf.

Using printf is like using a machine gun to fire one bullet.

Another recursive approach:

# change directory to target folder:
cd /Volumes/path/to/folder

# find all things of type "f" (file), 
# then pipe "|" each result as an argument (xargs -0) 
# to the "xattr -c" command:
find . -type f -print0 | xargs -0 xattr -c

# Sometimes you may have to use a star * instead of the dot.
# The dot just means "here" (whereever your cd'd to
find * -type f -print0 | xargs -0 xattr -c

In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.

import javafx.fxml.Initializable;

class MyController implements Initializable {
    @FXML private TableView<MyModel> tableView;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        tableView.getItems().addAll(getDataFromSource());
    }
}

Parameters:

location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized. 

And the note of the docs why the simple way of using @FXML public void initialize() works:

NOTE This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.

You can use Collections.sort and pass your own Comparator<ActiveAlarm>

Use this function to remove specific arrays of keys without modifying the original array:

function array_except($array, $keys) {
  return array_diff_key($array, array_flip((array) $keys));   
} 

First param pass all array, second param set array of keys to remove.

For example:

$array = [
    'color' => 'red', 
    'age' => '130', 
    'fixed' => true
];
$output = array_except($array, ['color', 'fixed']);
// $output now contains ['age' => '130']

Delete the Intermediate folder after then run the project is working fine actually that APK builds to another system. Go to app/build/intermediates.

Try Carsh log app from android.

use the link to download app.

You can do this very easy, look my Supervisor recipe:

- name: Setup Supervisor jobs files
  template:
    src: job.conf.j2
    dest: "/etc/supervisor/conf.d/{{ item.job }}.conf"
    owner: root
    group: root
    force: yes
    mode: 0644
  with_items:
    - { job: bender, arguments: "-m 64", instances: 3 }
    - { job: mailer, arguments: "-m 1024", instances: 2 }
  notify: Ensure Supervisor is restarted

job.conf.j2:

stderr_logfile=/var/log/supervisor/{{ item.job }}.stderr.log
stdout_logfile=/var/log/supervisor/{{ item.job }}.stdout.log

Output:

dd-mm-yyyy hh:mm:ss.000 Universal sortable date/time pattern

In python, it's called slicing. Here is an example of python's slice notation:

>>> list1 = ['a','b','c','d','e','f','g','h', 'i', 'j', 'k', 'l']
>>> print list1[:5]
['a', 'b', 'c', 'd', 'e']
>>> print list1[-7:]
['f', 'g', 'h', 'i', 'j', 'k', 'l']

Note how you can slice either positively or negatively. When you use a negative number, it means we slice from right to left.

For a list of elements

List<string> lstTest = new List<string>();

lstTest.Add("test1");
lstTest.Add("test2");
lstTest.Add("test3");
lstTest.Add("test4");
lstTest.Add("test5");
lstTest.Add("test6");

If you want to copy all the elements

List<string> lstNew = new List<string>();
lstNew.AddRange(lstTest);

If you want to copy the first 3 elements

List<string> lstNew = lstTest.GetRange(0, 3);

I had this problem inconsistently between different platforms, as I got JSON as String from Mapper and did the writing myself. Sometimes it went into file as ansi and other times correctly as UTF8. I switched to

mapper.writeValue(file, data);

letting Mapper do the file operations, and it started working fine.

The smallest one I know is lighttpd.

Security, speed, compliance, and flexibility -- all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems. And best of all it's Open Source licensed under the revised BSD license.

I always find it conceptually easier to think of that you are making the this pointer const (which is pretty much what it does).

There are two ways you can do this. You can use the throw the values into a hash for a lookup table, as suggested by the other posts. ( I'll add just another idiom. )

my %bad_param_lookup;
@bad_param_lookup{ @bad_params } = ( 1 ) x @bad_params;

But if it's data of mostly word characters and not too many meta, you can dump it into a regex alternation:

use English qw<$LIST_SEPARATOR>;

my $regex_str = do { 
    local $LIST_SEPARATOR = '|';
    "(?:@bad_params)";
 };

 # $front_delim and $back_delim being any characters that come before and after. 
 my $regex = qr/$front_delim$regex_str$back_delim/;

This solution would have to be tuned for the types of "bad values" you're looking for. And again, it might be totally inappropriate for certain types of strings, so caveat emptor.

"%s%d%s%d\n" is the format string; it tells the printf function how to format and display the output. Anything in the format string that doesn't have a % immediately in front of it is displayed as is.

%s and %d are conversion specifiers; they tell printf how to interpret the remaining arguments. %s tells printf that the corresponding argument is to be treated as a string (in C terms, a 0-terminated sequence of char); the type of the corresponding argument must be char *. %d tells printf that the corresponding argument is to be treated as an integer value; the type of the corresponding argument must be int. Since you're coming from a Java background, it's important to note that printf (like other variadic functions) is relying on you to tell it what the types of the remaining arguments are. If the format string were "%d%s%d%s\n", printf would attempt to treat "Length of string" as an integer value and i as a string, with tragic results.

Tried in Hive and got the below output

5,chapie,Los angels,USA

Inner Join

SELECT * FROM table1 INNER JOIN table2 ON (table1.id = table2.id);

1 wqe chennai india 1 wqe chennai india

note: Only records in left table are displayed whereas for Left Join both the table records displayed

Ok, I am definitively late to the party but if you are still looking for an optimal solution I would use the following ( for Java 8 )

    Charset inputCharset = Charset.forName("ISO-8859-1");
    Path pathToFile = ....
    try (BufferedReader br = Files.newBufferedReader( pathToFile, inputCharset )) {
        ...
     }

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

This works for me.

@Test
public void cloneTest() {
    List<Part> parts = new ArrayList<Part>();
    Part part1 = new Part(1);
    parts.add(part1);
    Part part2 = new Part(2);
    parts.add(part2);
    try {
        ObjectMapper objectMapper = new ObjectMapper();
        String jsonStr = objectMapper.writeValueAsString(parts);

        List<Part> cloneParts = objectMapper.readValue(jsonStr, new TypeReference<ArrayList<Part>>() {});
    } catch (Exception e) {
        //fail("failed.");
        e.printStackTrace();
    }

    //TODO: Assert: compare both list values.
}

Since your divs are position:absolute, they're not really nested as far as position is concerned. On your jsbin page I switched the order of the divs in the HTML to:

<div class="child"><div class="parent"></div></div>

and the red box covered the blue box, which I think is what you're looking for.

Not sure that it will be applicable solution for you. But the only way for monitoring tomcat memory settings as well as number of connections etc. that actually works for us is Lambda Probe.

It shows most of informations that we need for Tomcat tunning. We tested it with Tomcat 5.5 and 6.0 and it works fine despite beta status and date of last update in end of 2006.

I've used the following script with great success on numerous servers:

pid=`jps -v | grep $INSTALLATION | awk '{print $1}'`
echo $INSTALLATION found at PID $pid 
while [ -e /proc/$pid ]; do sleep 0.1; done

notes:

• It's looking for a java process, so I can use jps, this is much more consistent across distributions than ps
• $INSTALLATION contains enough of the process path that's it's totally unambiguous
• Use sleep while waiting for the process to die, avoid hogging resources :)

This script is actually used to shut down a running instance of tomcat, which I want to shut down (and wait for) at the command line, so launching it as a child process simply isn't an option for me.

Use data type LONGBLOB instead of BLOB in your database table.

Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

$scope.$emit: This method dispatches the event in the upwards direction (from child to parent)

$scope.$broadcast: Method dispatches the event in the downwards direction (from parent to child) to all the child controllers.

$scope.$on: Method registers to listen to some event. All the controllers which are listening to that event get notification of the broadcast or emit based on the where those fit in the child-parent hierarchy.

The $emit event can be cancelled by any one of the $scope who is listening to the event.

The $on provides the "stopPropagation" method. By calling this method the event can be stopped from propagating further.

Plunker :https://embed.plnkr.co/0Pdrrtj3GEnMp2UpILp4/

In case of sibling scopes (the scopes which are not in the direct parent-child hierarchy) then $emit and $broadcast will not communicate to the sibling scopes.

For more details please refer to http://yogeshtutorials.blogspot.in/2015/12/event-based-communication-between-angularjs-controllers.html

OK, finally got it working: see https://github.com/angular/angular/pull/10314#issuecomment-242218563

In brief, you can no longer use name attribute within a formGroup, and must use formControlName instead

ImageMagick and GD can handle PNGs too; heck, you could even do stuff with nothing but gdk-pixbuf. Are you looking for a graphical editor, or scriptable/embeddable libraries?

I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.

In case this helps someone, this is the easiest way I found, without requiring admin rights:

• make sure the directory you want to install your packages into exists. If you want to respect the convention, use: C:\Users\username\R\win-library\rversion (for example, something like: C:\Users\janebloggs\R\win-library\3.6)
• create a .Renviron file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER variable to be your custom path:

R_LIBS_USER=C:\Users\janebloggs\R\win-library\3.6

(feel free to add comments too, with lines starting with #)

If a .Renviron file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile. You can read about it in help(Startup).

Now it should be persistent between sessions!

Holdover from C.

u should add a theme to ur all activities (u should add theme for all application in ur <application> in ur manifest) but if u have set different theme to ur activity u can use :

 android:theme="@style/Theme.AppCompat"

or each kind of AppCompat theme!

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

Use MacPorts:

$ sudo port install watch

This works for me :

$scope.array1 = $scope.array1.concat(array2)

In your case it would be :

$scope.actions.data = $scope.actions.data.concat(data)

Recently I came across a very similar problem. Just wanted to share our solution with you all. I wanted to I created an instance of a Car<CarA> from a json object using which had an enum:

Dictionary<MyEnum, Type> mapper = new Dictionary<MyEnum, Type>();

mapper.Add(1, typeof(CarA));
mapper.Add(2, typeof(BarB)); 

public class Car<T> where T : class
{       
    public T Detail { get; set; }
    public Car(T data)
    {
       Detail = data;
    }
}
public class CarA
{  
    public int PropA { get; set; }
    public CarA(){}
}
public class CarB
{
    public int PropB { get; set; }
    public CarB(){}
}

var jsonObj = {"Type":"1","PropA":"10"}
MyEnum t = GetTypeOfCar(jsonObj);
Type objectT = mapper[t]
Type genericType = typeof(Car<>);
Type carTypeWithGenerics = genericType.MakeGenericType(objectT);
Activator.CreateInstance(carTypeWithGenerics , new Object[] { JsonConvert.DeserializeObject(jsonObj, objectT) });
